Sophia Bush and Jamie Chung wear sexy black body coverings at the Los Angeles premiere of the opioid thriller “Junction.”

Sophia Bush and Jamie Chung don sexy black pants at the world premiere of their film Junction at the Harmony Gold Theater in West Hollywood on Wednesday.

Sophia slipped into an ankle-length cocktail dress with a long slit, gold straps on the straps and peep-toe cha-cha heels.

One-woman glam team Afton Williams gave the 41-year-old One Tree Hill alum big curls in her brunette mane.

Williams also brought out Bush's bushy brows, long lashes, kohl-lined eyes, pink blush and mauve pout.

Since October, the “Work in Progress” producer and host has been missing her friend Ashlyn Harris, who is caring for her 16-month-old son Ocean Maeve and her two-year-old daughter Sloane Phillips (with her estranged wife Ali Krieger).

Sophia – who filed for divorce from husband Grant Hughes in August – and the 38-year-old retired soccer star were last pictured together at an Art Basel event in Miami on December 7.

Instead, Bush received a kiss on the cheek from her former “One Tree Hill” co-star Bryan Greenberg, who made his feature film debut with “Junction.”

In the opioid thriller, out in limited U.S. theaters/VOD this Friday, the Southern California native portrays Allison, the troubled wife of Nebraska-born 45-year-old OxyContin-addict character Michael.

“I had to have routine surgery and I was prescribed OxyContin and I kind of got addicted and it was really hard to get off of it,” Bryan explained to Us Weekly on Tuesday.

“I wondered how a system was created to turn innocent people like me into addicts.” I just wanted to understand why seemingly good people do these terrible things. I was really more interested in the characters than the opioid part. It was the people I was more interested in, situated in this opioid world.”

Greenberg continued, “I really wanted to explore that and explore why you do the wrong thing for the right reasons.” The doctor who prescribed it [the pills] doesn't want to see her patients suffering anymore.

“This is a real, real problem.” And pain is subjective and your level of pain is different than my level of pain. So when someone says they’re at 10 and they want to prescribe them, they don’t want their patients to suffer.”

Meanwhile, Jamie showed off her midriff and legs in an ankle-length sheer tank dress with matching pumps.
